Hi JW, my experience was an increase in bass between 0.90 and 0.99, and now I think it's reduced at A0.4...although I think I need to do some more testing
Try A0.4 / A0.5 and feedback the results

Why do I get the feeling that these firmware updates are part of an increasingly elaborate social experiment??
Absolutely ! I've dusted off my Micromega Stage 2 CD player that now serves as a transport into the M-DAC (when the UnitiServe is elsewhere), and promoted my NVA AP50 to use as a power amp (volume set to 11).
I keep having to pause the music to go pick up my socks.
BTW. I'm finding vA.04 is the best so far, with no lack of bass weight. Also, the difference between OT XD and DD is now more pronounced, with XD clearly more - ah - clear to my ears.

Interesting feedback for us, while we are working blind as I dont have a High resultion audio system ATM completed the "Schematic development" of the M-AMP last week, so about to start the PCB design... but also have to get back to the BDAC now...John

John, I don't understand. I am already on A0.4 now. Do you mean try A0.5? Any tweaks done on A0.5? Sorry for so many questions. Just like to know more of any changes between 0.90 and A0.5..

We are interested if there's any SQ difference between A04 / A05
There have been HEAPPPP's of changes between 0.90 and A04/A04.
Bug fixes, added features and trying to implement "work arounds" for the ESS left channel locking design bug...

I will if you tell me it sounds better
I wish I could, but ATM I dont have a decent system to tell....
But half of the users prefer 0.90/0.96 sound and the other half 0.99...
I prefer the earlier... 0.90/0.96 SQ...
OK, but were any of those changes specifically designed to improve the SQ ? Of course, I love listening for myself, but it would be useful to know what you are aiming for.
For example, as mentioned earlier, I find the difference between OT XD and DD more pronounced. Is this a side effect of changes to resolve bugs, or a designed improvement ?
Thanks John,
Jan

Replace the relay - or just cycling the relay might "free" it mechanically... Its a simple Mechanical device which is "Sticky"

If you're still in the UK feel free to pop over to mine, I've got two fairly 'HD' headphone setups

Hi Jan,
No not yet - but second order effects have effected the SQ (with opposing opinions as to which is better!!!).
John
Noted and Thanks. Do keep me in the loop if the MPAX is ready for pre-order.

Thank you for the offer - back in Czech already,

If you decide to "live with your unit" as it is, then I can replace the relay when we update it to M-PAX spec.
Hi John,
That's clear. I hadn't fully grasped that you're unable ATM to adequately listen to your work. The mind boggles to think of what you'll achieve when you're fully set up with a high-res system.
Meanwhile, more than glad to be a guinea pig (lab rat ?)
Many thanks

Indeed
If it resolves itself by cycling the relay, then I will replace the relay as a "Safe guard"
